Effect of Different Seed Processing Methods on Seed Recovery and Seed Quality of Onion cv. Arka Kalyan

Standardization of Screen Aperture Size for Processing of Seeds of Chilli (Capsicum annuum L.) Hybrid UARChH42 (JCH42)

“…This may be because of retention of bolder seeds on screen aperture size with optimum size which constitutes of higher physiological attributes within seeds; higher initial food reserves in the larger seed, greater embryo size, and more ability to utilize the metabolites that promoted better seed germination and other quality parameters S 1 = 0.90 mm oblong; S 2 = 0.80 mm oblong; S 3 = 1.80 mm round; S 4 = 2.00 mm round; S 5 = 2.10 mm round Similar results were observed by Kumar et al, (2014) in green gram, Angadi and Kumar (2016) in fodder sorghum, Lamani and Deshpande (2017) in onion and Ganiger et al, (2018) From this study it can be inferred that the per cent germination recorded in both 2.10 mm and 2.00 mm round treatment was higher than the Indian Minimum Seed Certification Standards and also 2.00 mm sieve had more seed recovery per cent values as well as all the seed quality parameters than 2.10 mm and other sieve size. Hence, it can be inferred that the 2.00 mm round sieve can be considered optimum for processing of chilli hybrid UARChH42 (JCH 42) seeds to obtain highest seed recovery, with requisite physical purity, germination, seedling length and seedling vigour index.…”
